Maintaining Your Phone's Peak Performance For the best care of your phone, only authorized personnel should service your phone and accessories. Allowing unqualified personnel to service your phone may result in damage to your phone and may void the warranty. There are several simple guidelines to operating your phone properly and maintaining safe, satisfactory service. • To ensure that the Hearing Aid Compatibility rating for your phone is maintained, secondary transmitters such as Bluetooth and WLAN components must be disabled during a call. • If your phone is equipped with an external antenna, hold the phone with the antenna raised, fully-extended and over your shoulder. • Do not hold, bend or twist the phone's antenna, if applicable. • Do not use the phone if the antenna is damaged. • If your phone is equipped with an internal antenna, obstructing the internal antenna could inhibit call performance. • Speak directly into the phone's receiver. • If your phone has a SIM or memory card: (i) handle the SIM or memory card with care, (ii) do not remove a card while the phone is transferring or accessing information, as this could result in loss of data and/or damage to the card of phone, (iii) protect cards from strong shocks, static electricity, and electrical noise from other devices, and (iv) do not touch gold-colored contacts or terminals with your fingers or metal objects (if dirty, wipe the card with a soft cloth). 237
